It's obviously not possible to put a full list in the taxobox, so I've chopped it to reduce the width.

The alternative would be to keep the scientific names in the box, and give a fuller list outside. jimfbleak 16:25 25 May 2003 (UTC)

As of right now, as far as I can tell... there's some sort of vandalism on this page. I think this may be a server issue. Someone delete this when it doesn't apply, but....--Bic1313 17:02, 4 September 2006 (UTC)

[edit] Suborders of Carnivora

I don't believe the suborders shown are generally accepted. While I am no expert, I have done some reading and I believe the generally accepted classification uses the suborders Arctoidea (or Caniformia) and Aeluroidea (or Feliformia). This classification reflects common ancestry rather than obvious physical similarities. The pinnipeds are contained within the Arctoidea, and apparently share a common ancestor with bears.

Hello, is this article only for extant species/families, or can I add extinct taxa? I would agree with the comment above incidentally, I always used arctoidea & aeluroidea. Amphicyonid

The Arctoidea clade does not include Canidae, therefore it cannot be considered equal in status to Caniformia. Caniformia split into Canidae and Arctoidea 37-40 mya; then, after Ursidae split off, Pinnipedia and Musteloidea split. Pinniped fossils go back 25-27 mya. Ursidae was the first family to split from the Arctoidea lineage, so yes they do share a common ancestry. Valich 03:03, 16 February 2007 (UTC)

It was changed recently. In my opinion the "grrrrrr!" balloon is a bit out of style on a scientific page. Seems like someone's joke in a wrong place. Paul Pogonyshev 23:30, 3 Aug 2004 (UTC)

[edit] Suborders

I am rather dubious of the monophyletic monomania that often appears on wikipedia. If we are to use the normal hierarchic taxonomic groupings at all (which we obviously are), we have to accept that there will be paraphyletic groups. As such, I don't see why grouping Fissipedia and Pinnipedia as separate suborders of Carnivora is any more problematic than grouping Aves as a separate class of Vertebrata from Reptilia, which we do. On my understanding of reptilia, the current grouping of Carnivora would be analogous to us creating one class consisting of Aves and most of the reptiles, and a separate class for turtles. Which we do not do. The Pinnipeds are still considered, so far as I am aware, a monophyletic group which is quite morphologically distinct from the other members of Carnivora. I fail to understand why the three Pinniped families should simply all be listed together as families of "Caniformia" as though they are no more closely related to one another than they are to dogs or bears. john k 02:51, 26 August 2005 (UTC)

Anybody out there? It's been months and months since I wrote this, and no response. This is quite irksome. john k 21:58, 5 April 2006 (UTC)

According to Wiki Article Pinnipeds, with cited reference, "Pinnipeds appear to have diverged from their bear-like ancestors during the Latest Oligocene. The earliest fossil pinniped that has been found is Enaliarctos, which lived 24–22 million years ago, at the boundary between the Oligocene and Miocene periods. DNA evidence suggests that all modern pinnipeds descend from a common ancestor that lived sometime in the earliest Miocene, possibly an Enaliarctos-like mammal." Valich 05:22, 15 February 2007 (UTC)

[edit] Phylogeny

I've added a large piece of information on carnivore relationships. English is, however, not my native language. SO CAN PLEASE SOMEONE CHECK THIS PARAGRAPH, AND CORRECT THE SENTENCES IF NECESARRY? Thank you. DaMatriX 13:45, 25 October 2005 (UTC)

[edit] Red panda?

I thought red panda was Ursidae??--Sonjaaa 03:36, 28 April 2006 (UTC)

"The progenitors of raccoons and bears split during the Oligocene (24-38 mya), and within 10 million years the red panda lineage diverged from the raccoon lineage. In the Miocene (5-23 mya), there were three major radiations among the bears, the earliest line leading to the giant panda, the second to the South American spectacled bear, and the last to the six other bear species." Schaller, George B. (1993). “The Panda is a Panda,” an excerpt from The Last Panda. University of Chicago Press. Online at: http://www.press.uchicago.edu/Misc/Chicago/736296.html. Red Pandas split from the raccoon lineage: current Family Procyonidae, Superfamily Musteloidea. Giant Panda split from Ursidae. Musteloidea and Ursidae both evolved from Caniformia but split from the lineage at different times (different species). Valich 05:40, 15 February 2007 (UTC)

[edit] Nearly all others mammalians are carnivora?!

..."nearly all others eat meat as their primary diet item: some (like the cat family) almost exclusively, others (like the..." Where are horses, sheeps, bulls, buffalos... etc? Pérez 20:54, 11 July 2006 (UTC)

The article refers to members of the Carnivora, not all mammals. Horses, sheep, etc., are not members of the Carnivora. Graham 23:07, 11 July 2006 (UTC)

[edit] Point of Confusion re: Arctoidea

"The pinnipeds form a clade with the bears to form the Arctoidea superfamily. The arctoids form a clade that includes another superfamily ... the Musteloidea."

This seems to be saying that one superfamily is nested in another, which couldn't be.

Understandable because Flynn's abstract is kind of muddled as well: "We further have determined the relative positions of the major lineages within the Caniformia, which previous studies could not resolve, including the first robust support for the phylogenetic position of marine carnivorans (Pinnipedia) within the Arctoidea (as the sister-group to musteloids [sensu lato], with ursids as their sister group)."

But if you look at the graphic in the article, it's clear that the Pinnipedia, Musteloidea and the ursids are all included in Arctoidea. If Pinnipedia and Musteloidea are superfamilies, than Arctoidea would have to be a higher-level taxon.

In Flynn's gram Pinnipedimorpha (pinnipeds) and Ursoidea (bears) form two clades that comprise Ursida. Ursida and Mustelida form Arctoidae. Ursida is a sister group to Mustelida. The graphic in the article needs to be rewritten and regrouped:

[edit] Caniformia?

why are usidae (bears) put in the group of caniformia? Both my current and ex science teachers agree that is does not fall into either of the groups.

There are four primary monophyletic clades within the extant Caniformia group: Canidae, Ursidae, Pinnipedia, and Musteloidea. The current phylogeny tree, after Wyss & Flynn, 1993, McKenna & Bell, 1997, Alroy, 2002, Wesley-Hunt & Flynn, 2005, and Wesley-Hunt & Werdelin, 2005 is:

[edit] Updating Carnivora, starting with Feliformia

I will be updating the Carnivora taxa articles shortly, to match the listing in MSW3. I have previously updated many of the other mammalian orders in this way. However, I see there is plenty of disagreement in the taxonomy. I will try to use a gentle touch in editing the articles. However I thought it prudent to post here my intentions. You can also see the MSW3 taxonomy at User:UtherSRG/Carnivora. - UtherSRG (talk) 00:31, 14 January 2007 (UTC)

The inclusion of Arctoidea elevates the status of Ursidae (the first to branch off). Ursidae, Pinnipedia and Musteloidae all evolved from Arctoidea. See cladogram on page 2 in Finarelli, John A. 2006 "Estimation of Endocranial Volume Through the Use of External Skull Measures in the Carnivora (Mammalia)." Journal of Mammalogy, Vol. 87(5) pp. 1027-1036. online at: http://home.uchicago.edu/~johnf/pdf/Finarelli_JMamm_2006.pdf Any thoughts on how to list Carnivomorpha, the Superfamily Miacidae, and the ancestral Parent Infraorder Miacoidea, with Carnivora? Valich 02:48, 16 February 2007 (UTC)
Nope, no thoughts. I should have said I'm updating the taxonomy for families down to species. MSW3 doesn't deal much with how the families are related. - UtherSRG (talk) 11:49, 16 February 2007 (UTC)
I'm glad you left Arctoidea in: it helps clarify the phylogeny relations, and also addresses a couple of the above discussion concerns. Are you thinking about adding species here? There's thousands in the MSW3 - too cluttered. What do you think about replacing Family Miacidae with Superfamíly Miacoidea instead? The Portugese Wiki has it like this:*** Superfamíly †Miacoidea (34-64 Ma)****Family †Miacidae**** Family †Viverravidae Valich 22:00, 16 February 2007 (UTC)

[edit] Classification/Cladogram

I've been trying to update the Feliformia a bit by adding superfamilies and other clades between the suborder and family levels. The Caniformia already has this, because the phylogeny of this suborder has been well established in the last few years. The exact phylogeny of the Feliformia is, however, still in doubt. Nonetheless I decided that in the case of the Feliformia, some form of classification between that of suborder and family is necessary, in order to keep things clear to the reader. However, there should be a note in the article that the exact phylogeny of the Feliformia is still not conclusively established.

So, I decided to follow the phylogeny that is based on the most recent data. As such, several things has been altered. The first thing is the exact classificaton of animals that are truely cat-like: the Nimravidae has now become the Feliform outgroup, the Barbourofelidae are given their own family related to cats and the Prionodontidae are taken out of Viverridae and are also placed close to the cats. Barbourofelidae, Prionodontidae and Felidae thus form a monophyletic group known as Feloidea. As a result, all other (extant) families form a monophyletic group is well, which is known as Viverroidea. Within the Viverroidea there is another clade that excludes the Viverrids, but includes the mongoose- and hyena-like animals. I could not find the name of this clade, so I decided to name it Herpestoidea, because the Herpestidae form the crown-group (if I understand the rules of naming superfamilies correctly).

I'm sorry I post this comment a few days after I altered the article. If everyone agrees with the changes, can the Cladogram at the bottem of the article be altered with the edits that are outlined above?

[edit] "false sabre-tooths"

Wouldn't be more appropriate to call them "false sabre-tooth cats"? Since they do have "legitimate" sabre teeth, but they're not cats, though they look like? --Extremophile 20:13, 19 March 2007 (UTC)

Yes, I agree. They don't have false sabre-tooths.....their tooths are real enough. They are false sabre-tooth cats. Sounds logical to me (hmm that sounds like a Vulcan..;))DaMatriX 00:05, 20 March 2007 (UTC)

[edit] The List

I the list which is mention at the "See Also" section, were the list is red, I think I'll start the list. The reason why I'm telling this because we need to the world the list and also I don't want ton be acused. User:4444hhhh

I've redirected it to the existing list of carnivores.... within the list of placental mammals. - UtherSRG (talk) 14:13, 24 March 2007 (UTC)

Well, I made a different page, if it's thats find with you. User:4444hhhh

It's not. No need to have to keep both pages up to date. Deleted your page, reverted your change to this one. - UtherSRG (talk) 22:45, 24 March 2007 (UTC)

Yeah but, the palcental mammal list also includes other mammal orders, that's why I think it should be seprated. And why did you did that! I have work hard on that list, and the Cetcean has its own list, so are you going to deleted it also, I don't think so! User:4444hhhh

You shouldn't have created it in the first place. I'll have to look at the Cetacean list, and perhaps redirect it, too. - UtherSRG (talk) 23:29, 24 March 2007 (UTC)
Ah... now that I've refreshed my memory and visited the Cetacean page.... no. It is quite fine as it is way more than just a list. But I think there are way too many Carnivora species for such a page. - UtherSRG (talk) 23:42, 24 March 2007 (UTC)

Listen, after thinking about it, I'm sorry, will you forgive me? Me acting like a big jerk, I just want the page to be great. Sorry.User:4444hhhh

[edit] Extinct families

I've added two extinct families to the family list. The first is the commonly recognised Enaliarctidae, a family of primitive Pinnipeds. Second is the (somewhat disputed) family Hemicyonidae, which is more and more considered a seperate family closely related to bears, instead of being true bears (Ursidae). To my knowledge, these were the only Carnivora families (extinct or extant) that were missing in this article. So, the family (phylogenetic) list is now complete. DaMatriX 22:19, 26 March 2007 (UTC)

[edit] Screwed up cladogram

In an attempt to edit the cladogram, reflecting the recent changes, I managed to screw things up completely. I'm full of frustration right now: after more than an hour of editting I just can't find the mechanism behind the nice cladogram at the main page. It looks real simple, but every time I edit something, the whole thing screws up. Aaarghhh!!! Can comeone PLEASE fix the cladogram for me, before I'm going to throw my keyboard through my monitor?

(The bottleneck is the Pinnepedia clade) DaMatriX 21:04, 28 March 2007 (UTC)

What do you need done? - UtherSRG (talk) 21:17, 28 March 2007 (UTC)
Ok, I think I have what you want. - UtherSRG (talk) 21:32, 28 March 2007 (UTC)
